I just expected that that script contains all, and does not require additional scripts.
Not sure about this scripts:.

require 'CONFIG_ROOT/general-functions.pl';
require "${General::swroot}/lang.pl";
require "${General::swroot}/header.pl";

I tried run script, get Internal Server error. Provider also checked script and say, that this error appears when the script is run:

root@web1 cgi-bin# sudo -u gareks ./ipinfo.cgi
Unterminated <> operator at ./ipinfo.cgi line 90.

here is full code:
